[Talk-GB] Other Route with Public Access (ORPA)

[Dave F.]

Hi

I've noticed a couple few ways being tagged with designation= Other 
Route with Public Access (or just ORPA)

I've never seen a route signed with this on the ground or in the OS 
Opendata set, only on OS printed maps.

If this is the case I believe it's illegal mapping & should be removed. 
Is this correct or have I missed something?

Cheers
Dave F.
